| Why is it necessary to have gear on the same phase from electrical panel? The only thing I can think of that would improve things is to keep all the noisy stuff on one side of the panel, like refrigerator, and the cleaner stuff on the other side. Its a myth... No such thing. IF the electrician did his job right and f... | |
| Toroidal vs EI power amps any difference. Toroids are prone to mechanical buzzing, vibrating, when fed from AC mains with DC on the Line. Especially large VA Toroids used in power amps. For smaller VA toroids you can buy a plug in DC blocker that will filter out the DC on the mains and in... | |
| Advice on Repairs for Audio Research VT100 Mk II @77jovian The ARC VT100 MK III does not require the 6922 input and driver tubes to be biased. Only the output power tubes need to be biased... It can take hours to bias the 6922 tubes in a VT100 or VT100 MK II... http://mycollins.net/audio/art... | |

| Wall socket for Ethernet/ Cable outlet recommendation jea48 3,951 posts 11-23-2022 at 05:25pm I like Panduit brand for the Ethernet RJ45 data jack. The RJ45 CAT number jack you use depends on the Cat number of the 4 pair twisted cable. Example, if the cable is CAT 5e then use ... | |
| Advice on Repairs for Audio Research VT100 Mk II There are 8 power tube 100 ohm 5% 3 watt screen resistors. (Part # 43100208) ARC uses the resistors as fuses. The wattage value should never be increased. There are 8 power tube plate 1 ohm 2 watt 5% BLUE LINE resistors. (Part #43100004.) https:... | |
| Advice on Repairs for Audio Research VT100 Mk II @edward78 The VT100 MK II first came out in 1998 though 2000, (maybe through the spring of 2001). The amp is at least 21 years old. I am surprised the Tech that gave you the price for the repairs didn’t mention that. How about the electrolyti... | |
| Advice on Repairs for Audio Research VT100 Mk II @edward78 said: I’m fine with the price of the resistors, 6550 tubes, and labour but the price for the 6992 tubes seems too high. On the JJ Tubes website, these tubes sell for about EUR 20 a piece and they do not even offer matched sets of 6992.... | |
| Another dedicated circuit question Different potentials always try to equalize to the same potential thus there will be current flowing between the two (or more). It will always use the path of least resistance. The current will take any path that is provided... As for using mo... | |
| Another dedicated circuit question @immatthewj said: I was ASSUMING that a 20A breaker should not only be in front of, at minimum, 12 gauge wire, but also a 20A breaker. That is correct. The breaker determines the ampere rating of the circuit. 20A breaker, 20 amp branch circuit... | |
| Another dedicated circuit question @immatthewj , on page 3 of the instruction manual (pdf) is where it says to connect it to a 15A outlet. "4. The PST-8 should only be connected to a 120 VAC, 60Hz, 15 amp grounded electrical outlet." "Connected to a 120V 60Hz 15 amp grounded ... | |
| Another dedicated circuit question @immatthewj I found out that three dedicated lines was another mistake I made. Not really... If the correct type of branch circuit wiring is used, and the correct method of installing the branch circuit wiring is used. I have two dedicated ... | |
| FUSE Question...Very Confused Please Help ! @ieales The amplifier is designed in Germany. EU has 230V AC mains power. As stated the amplifier is made to be fed by 230V or 110V. The odd thing, at least to me, is the 110V mains feed. Not sure how the designer arrived at 110/230V. Usually ... | |
| FUSE Question...Very Confused Please Help ! Owner manual specs: 500VA Max power consumption. 500VA / 110V = 4.55A. The designer of the amp only bumped the fuse up 110%. 4.55A X 110% = 5A. A 5A slow blow fuse seems a little tight to me for the amplifier... 500VA / 230V = 2.18A X 110% = 2.... | |
| FUSE Question...Very Confused Please Help ! @rocky1313 From page 6 of owner manual: V S – Mains Voltage Switch (12) VOLTAGE SELECTOR The Penta 5.1 amplifier can be used in all countries and is good both for 110/115 and 220/230 V. Before the first operation, please make sure that ... |
